Nozzles that should be angled 15-45 degrees from horizontal include:

Explanation:
The spray patterns of these two nozzles are optimized when the nozzle is tilted slightly upward, not held level or steeper. Angling raindrop and whirl chamber nozzles about 15–45 degrees from horizontal helps form a fine mist rather than a solid jet. This orientation promotes better air entrainment and keeps small droplets suspended longer, which improves cooling and area coverage. If you keep the nozzle too close to horizontal or too steep, the droplets become larger or the spray concentrates in a narrow area, reducing effectiveness. So both raindrop and whirl chamber nozzles benefit from being angled within that range.
